Artbooks of Aria

Obviously an introduction for the series and contains character guide,
story guide, staff/cast interviews etc. If you are after artworks,
this is not for you. But, for those who want to know the
background, it's an excellent reading.

This is a collection of colour illustrations by Amano Kozue. It's not
Aira-specific but there are 16 pages for Aria and 14 pages for
Aqua. I really love the frontispiece, a deformed version of Akari,
Aika and Alice ^_^
